I believe I have two problems, first one when accelerating I get a squeal that used to be only when I reached 30mph but now it is constant. It is extremely loud when I take my foot off the accelerator on a downhill. Also when I am driving any faster than 55mph and I get to like an equalibrium with the accelerator the car starts to almost grind beneath me and vibrate very loud. I believe its a u-joint? Now for number 2, when I am turning at slow speeds I get a squeal/squaking noise that almost sounds like its coming from near the drivers front wheel? I have not had any work done to it to make this noise occur, totally random. Please help. Thanks.

 

what year man??

 

I have a 1998 4.0 with 137k miles. I also just changed the differential fluid and im not sure if that caused it to quit squealing or if when i got under the car to see if there was play in the front propeller shaft i wiggled it and it got stuck and the squeal has gone away but now when i turn at low speeds there is a rapid clunking noise, and vibrations almost like a grinding underneath me when im driving.

 

sounds like at axle shaft, they have constant velocity joints, if it goes bad youll get a clunk when turning, figure out what side and replace it, dont let it go too long as to itll cause major trouble if it brakes
